South Dakota: Revocable Living Trust Creation Requirements

Requirements one by one

Intent, subject, purpose, and beneficiary

South Dakota uses its own trust statutes rather than the Uniform Trust Code.
Under SDCL § 55-1-4, the trustor creates an express trust as to the trustor and
beneficiary through any words or acts showing with reasonable certainty an
intent to create the trust and its subject, purpose, and beneficiary. Section
55-1-1 permits any purpose for which a contract may lawfully be made.

SDCL § 55-1-12 includes a present or future, vested or contingent beneficial
interest in its beneficiary definition. Section 55-1-46 recognizes lack of
contractual capacity, fraud, duress, undue influence, mistake, forgery, and
execution irregularity as probable-cause grounds for a trust contest despite a
no-contest clause. It does not state a separate age or will-capacity formula.

Creation and trustee acceptance

For a separate trustee, § 55-1-5 requires words or acts indicating with
reasonable certainty acceptance or a consideration-supported acknowledgment
of the trust's existence, plus the subject, purpose, and beneficiary. Section
SDCL § 55-3-2 says the trustor's and trustee's mutual consent creates the trust, and
the beneficiary may take advantage of it before rescission.

These rules do not impose a universal document form for personal property.
Section 55-1-4 expressly adds written evidence when the trust concerns real
property. The statute does not state a universal signature, witness, or notary
requirement for the ordinary trust itself.

No initial property requirement

South Dakota rejects the usual assumption that every trust must start with an
identified corpus. Section 55-1-55 says a trust remains valid and enforceable
when unfunded, when it initially has no res, corpus, or asset, and even when its
res is not ascertainable or identifiable at creation. No trustee, protector,
or advisor has a duty until the trust has property.

That rule concerns trust validity. A particular deed, account registration,
assignment, delivery, or beneficiary designation may still be required before
the trust controls that asset.

Settlor as trustee and beneficiary

Section 55-1-15 expressly prevents invalidity, merger, or termination when the
trust names one or more successor beneficiaries at the trustor's death and the
trustor is sole trustee and sole beneficiary during life. It similarly covers
multiple trustors when one or more are trustees and the lifetime beneficial
interest is held by one or more trustors.

Revocability

South Dakota's default runs toward irrevocability. Section 55-3-6 makes the
trust irrevocable unless its terms expressly reserve to the settlor a power to
revoke or modify. The section states no universal signed-writing-and-delivery
fallback, so the trust should state both the reserved power and its exercise
method.

Registration and real-property recording

Registration is optional. Section 55-1-56 says a trustee whose principal place
of administration is in South Dakota may register in the court there. SDCL
§ 55-1-57 requires the registration statement to identify the trustee and trust,
acknowledge the trusteeship, list other fiduciaries, and submit to court
jurisdiction while registered.

Real-property recording is separate. SDCL § 43-28-15 gives a properly recorded
instrument constructive-notice effect. Under § 43-28-17, an earlier
unrecorded conveyance can lose to a later good-faith purchaser or encumbrancer
for value whose conveyance records first.

What trips people up

“Valid without assets” does not mean a trust schedule automatically transfers
every listed asset. Section 55-1-55 validates the trust before funding; it does
not replace the separate transfer law for a home, account, security, or other
property.

Common questions

Must a South Dakota living trust be notarized?

Not under the cited general creation statutes. A real-property trust needs
written evidence, and the separate deed or recordable instrument follows its
own execution and recording law.

May I be the only trustee and current beneficiary?

Yes, when the trust provides for one or more successor beneficiaries at your
death. Section 55-1-15 says that structure is not invalid, merged, or
terminated.

Is court registration required?

No. Section 55-1-56 says the trustee may register at the principal place of
administration.
